On Januaray 8th and 9th, The Committee of Steel Structure Experts in China has hold the annual meeting in Wuhan, Hubei Province. More than 200 steel structure experts get together and discussion the current steel industry in China. They proposed to develop steel construction so as to defuse the current serious excess steel production capacity. The characteristic ofsteel construction is light, fast ,better and cheaper to use, the experts believes that structural steel is the most suitable for building industrial steel building construction.
During the meeting, the multi-site large-span grid structure is strongely suggested. Also, in order to facilitate the production of prefabrication, a six tetrahedral units of reticulated spherical shell is brough up. According to the latest reportes, eighty percent of steel building components can be processed in the factory, at the same time it is easy to dismantled. Moreover, some products and materials can be reused and recycled. Compared to the traditional concrete construction, steel construction can reduce 40% of weight, increase four times of construction efficiency, shortened 1/3 construction period, reduce 35% of carbon emissions, and also increase 5% of room rate. Therefore, steel structure is more popular in the developed countries.
Statistics showed that in the last five years, the amount of steel construction in China is 30 to 50 million tons which is accounting for 5% of steel production totally in Chinese Steel Industry. However, compared with other developed countries, it is very obvious that in China the steel construction application is still in a very low level. The steel construction proportion is over 45% in United State, 28% in Japan, 22% in Germany. Academicians in this meeting believe that developing steel construction can resolve the overcapacity in the Chinese Steel Industry, also it cvan promote the construction of industrialization, to achieve the transformation and upgrading of traditional industries.
